 +One of the human body's master [[cell]]s, with the ability to grow into any one of the body's more than 200 cell types. ​
 +Stem cells contribute to the body's ability to renew and repair its [[tissue]]s. Unlike mature cells, which are permanently committed to their fate, stem cells can both renew themselves as well as create new cells of whatever tissue they belong to (and other tissues).
 +Bone marrow stem cells, for example, are the most primitive cells in the marrow. From them all the various types of blood cells are descended. [[Bone marrow]] stem-cell transfusions (or transplants) were originally given to replace various types of blood cells.
